1. Sustainable food packaging based on polyhydroxyalkanoate
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER
2. A Study on Lignin or Zein Based Hydrophobic Coatings
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. LÄS MER
3. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. LÄS MER
4. Investigating the influence of moisture and temperature on adhesion and barrier properties in laminates
Master-uppsats, Lunds universitet/FörpackningslogistikSammanfattning : A world leading food processing and packaging company, Tetra Pak works with the vision of ‘Protect what’s good’ and aims to be a pioneer in developing sustainable packaging. Tetra Pak offers a wide range of carton packaging out of which aseptic carton packages are the most common. LÄS MER
5. Stretchable Barrier Coatings For Fiber-Based Materials : A laboratory study into the development of extensible/stretchable barrier coatings with nanoclay implementation, focusing on water vapour barrier properties.
Master-uppsats, Karlstads universitetSammanfattning : Executive summary Today, packaging has gained a significant role in the food industry as well as other industries. Paper substrates that have been coated in some ways are typically used to make packaging. The amount and type of pigment used in the formulation determine whether this coating is a pigment coating or a barrier coating. LÄS MER
